Microsoft's Xbox One S will come with a factory overclock of around 7% on the GPU core, potentially preventing some performance dips in games.

On the CPU side, the Xbox One S delivers the same 1.75GHz clock speeds as the original Xbox One, but the Xbox One S has a 7% GPU overclock, upping the GPU clock speeds from 853MHz to 914MHz and upping the ESRAM bandwidth from 219GB/s to 204GB/s.

Below you can see a table comparing the specifications.

These performance boosts will be minimal when compared to the original Xbox One, though the differences will be noticeable in some games, especially if they use dynamic resolutions or in games which frequently dip below a set framerate cap.

The lack of any CPU clock speed boosts does prevent the Xbox One S from outperforming the original Xbox One by a significant margin in most games, though it is still worth noting that the Xbox One S beat the Xbox One in all scenarios tested by Digital Foundry. You can see their testing in the video below.

All in all the Xbox One S is an improvement over the original Xbox One, coming in with a smaller form factor, 4K Blu-ray support and support for HDR content when it is available.

The increases in GPU and ESRAM clock speeds are to help the Xbox one with these high-resolution features, though were achieved due to the maturation of the manufacturing process for the AMD SoC used in the console. Over time production yields improve for these chips and higher clock speeds are achievable, which is why rereleasing older CPU and GPU hardware with increased clock speeds has been a popular tactic in recent years.
